10 days. The only good part of matchmaking is ranked, but the constant matches of solo players against teams of four have really put me off ranked for a while (the maps are trash, too). I mean for -blam!-'s sake I'd carry my team game after game in team arena yet I'd always lose to parties. Warzone is boring and social might as well be ranked at this point. The only main Halo I spent less time in was Halol 4.

I have about 170 hours. Most of those were put into playing a crap ton of custom games once the custom browser became available or warzone firefight

Maybe 2 hours. I hate how everything is gotten from loot boxes. I'm not playing H6/Infinite if they have ANY MTX or loot boxes. I'd rather have paid map packs.

I have about 226 hours, I think it’s a pretty fun game 🤷🏻‍♂️

30 days? I have 85 days in ARK: Survival Evolved. Maybe 10 hours in H5. I have a friend who is been running an H5 clan for 10 months, and he has 90 days.

Enough to the point where I'm SR 146 and have at least three dozen of every legendary req in the game

I think I played a whopping 3 online matches after beating the campaign and then decided to shelf it.

I’m sure I have over 80 hours. I wish I had more... too damn busy with work.

I think im just under 80 hours. Id also play more but I'm consistently surrounded by idiots when i play. Then i despise damn near every map.

Less than 200 hrs according to Waypoint. I burned out before I unlocked the Halo 2 BR.[spoiler]Warframe is a much better grind.[/spoiler]

More than most games, less than most Halos.

I stopped around like 100 hours or so because I was just done. My first run through of the campaign, (which I did on legendary because I've been playing Halo for a long time and its not that difficult) was so easy. No first run through of a campaign on the hardest difficulty should be that damn easy. There was only one mission that somewhat caused issues but on legendary in every other Halo game every mission has some spot that absolutely sucks and takes time to get through. Halo 5 lacked that. The req system ruined the game for me entirely. Absolutely horrible. I dont even think I need to explain why a system like that doesn't belong in Halo Game physics. Everything about the game's physics sucks and Im going to leave it at that. Weapon changes. All the weapon changes except for the Assault Rifle, Shotgun, Boltshot, and Suppressor sucked. All the Forerunner weapons pretty much were ruined although props to 343 on the splinter turret and grenade. But everything else felt horrible especially the DMR and Battle Rifle. Absolutely horrible. And don't even get me started on the Magnum, that change was the stupidest and most unnecessary one out of all of them. Its far too strong for a pistol, especially when that pistol is being used against a Spartan. The way it was in the other Halo's was fine. Art style change was bad for the most part although the vehicle art style and art style of certain areas were good but overall it wasn't. 343 should've stuck with the Halo 4 style and just improved the graphics, not completely change it. The ranking system in PvP is horrendous. I had a season where I won 9/10 of my FFA matches by 5+ points and I was placed in Gold. That's complete and utter BS. Winning 8/10 matches should automatically put you in Diamond for obvious reasons. Now Forge mode was amazing and very impressive. Whenever I get on Halo 5 thats all I do because its more fun than anything else. Team Action Sack is alright, Forge definitely makes it amazing but again all the above points about the game itself ruin it. Warzone. I hate it because I lost every time because I had noob team after noob team after noob team. I should not be put with that many scrubs that often when Im finishing a season with each ranked playlist being at top of platinum or higher. Lack of SBMM or if it does have it, poor SBMM ruined Warzone as did the req system. There's so much more I could add but not going too because I'm not making a comment that takes ten minutes to read.

0... don't have an Xbox or a pc regrettably.

I beat the campaign, so however long that is.

Campaign was horrible imo. Loved multiplayer though. Spent a good 3 days in total.

I have 131 days logged. No doubt most of that time was spent in Forge.

Totaling my playtimes, comes out to around 10.5 days, I think. But I haven’t played for over a year. Didn’t even download to my One X. Edit: 10.5 days seems too high, honestly. I don’t remember playing that much. Does 4.14:52:42 mean 4 days, 14 hours, 52 minutes, 42 seconds?

17.5 (I'm rounding since that's pretty much what it is) days. Doesn't include 3 in custom games though so 20.5 in total. Haven't played in a year and I deleted it, it's not the worst game out there but it's easily one of the most frustrating ones.

Just shy of 15 days. Most of it spent in warzone. Super fiesta and core play are my favorite social. Only do ranked team arena for the seasonal ranking(usually bronze/silver) love the multiplayer, best halo since h3, most fun since h2.
